tarakito Posted August 17, 2007 Report Share Posted August 17, 2007 Hey there, up to now i did all my molds (at least the 1 piece ones) the following way: I started with carving a prototype out of clay, sanded this down to 1000 and then polished it with some piece of cloth. I then glued it on some piece of plastic, built 4 Quote Link to comment Share on other sites More sharing options...
bassbug Posted August 17, 2007 Report Share Posted August 17, 2007 After very much use, RTV molds always start producing matt finish baits. Look at Poor Boy baits. Their baits have that matt look. It is a signature look for them. Not all bad. Try brushing your RTV mold with worm oil first. Also just using worm oil on the baits after you pour them works. I puchased some Silicone Oil and brush it into my RTV mold during and after I am done pouring baits, works great. Quote Link to comment Share on other sites More sharing options...
Smallie Posted October 1, 2007 Report Share Posted October 1, 2007 Has anyone ever tried Silicone aerosol spray to rejuvinate their RTV molds? All the sources I find for silicone oil want to sell you a gallon or more. Quote Link to comment Share on other sites More sharing options...
bassbug Posted October 1, 2007 Report Share Posted October 1, 2007 I bought a small jar. Let me see if I can find where I bought it and I will post it. Quote Link to comment Share on other sites More sharing options...
Kamakazee Posted October 1, 2007 Report Share Posted October 1, 2007 The finish of your master will be reproduced in the mold. Other words, your master must have a shinny finish to get it to show in the mold. If that helps. Quote Link to comment Share on other sites More sharing options...
SwampBaits Posted October 1, 2007 Report Share Posted October 1, 2007 Maybe u could try using devcon on the clay, to make it shiny. I know u don't want to use it, but plaster of paris would make you much more happy! Quote Link to comment Share on other sites More sharing options...

lure_learning Posted October 3, 2007 Report Share Posted October 3, 2007 If you use silicone oil on your molds isn't a pain to remove the baits? I would think the slipperiness would make it tricky to grab the baits. Quote Link to comment Share on other sites More sharing options...
bassbug Posted October 3, 2007 Report Share Posted October 3, 2007 I use just a little of the silicone oil, not a problem to get the baits out. Quote Link to comment Share on other sites More sharing options...
tubinator Posted October 3, 2007 Report Share Posted October 3, 2007 On your bait masters you might want to try painting them with thinned down epoxy (20 min epoxy plus alcohol) work the air bubbles out with your paint brush. As far as getting shiny baits out of the rtv molds, Jewelry supply stores offer silicone mold release spray. I'm a jewelry manufacturer and we used a product made by Castaldo called Jewelry Mold Release Spray. It is safe for rubber molds, food safe, Worker safe, and most importantly Non-ozone Depleting and non-explosive, it also works good on your fishing line to keep it limber and smooth casting.

Smallie Posted October 4, 2007 Report Share Posted October 4, 2007 Bassbug, thank you for the telephone number. I want the silicone oil to rejuvinate some used molds I bought on eBay. Tarakito, as others have suggested, when I make my own molds in RTV, I coat the baked sculpey masters with Devcon and get a smooth finish when I pour. I don't know how long this smooth finish holds up in production use. Quote Link to comment Share on other sites More sharing options...
tarakito Posted October 9, 2007 Author Report Share Posted October 9, 2007 hey up there! thanks for all your input - it``s highly appreciated. you`re right - my masters (made of clay) have some tiny scratches (caused by sandpaper, polishing, etc.) and therefore the baits didn`t come out shiny. i tried to cover up the master with epoxy which is a pain in the arse imho. so i tried pop molds which are much much easier to fabricate and cheaper. i think, taht i`ll stick to pop for now. cheers up, Ian.

longhorn Posted October 15, 2007 Report Share Posted October 15, 2007 My opinion is that matt finish baits look more natural...I would prefer all my molds produce a flat finish baits....in the water it makes no difference anyway. Quote Link to comment Share on other sites More sharing options...
Smallie Posted October 16, 2007 Report Share Posted October 16, 2007 Longhorn - I share that same opinion. The shiny baits are for catching fisherman. I will say that baits poured the same cup of plastic will look quite a bit different when one mold is matt finish and one is very shiny. The light reflection is different.
